While at home, he reunites with Ayano and the two attempt to piece together what happened with Yuichi and why Ayano herself jumped from the rooftop. A hindrance in their quest of discovery is Ayano's lack of long term memory. After her fall, Ayano can only remember 15 minutes of her past before it is forgotten and replaced by the next 15 minutes.

Can Naoya help Ayano with her vanishing memories? Will the supporting cast members of Chiaki, Sakura and a language teacher named Yukari be able to help? Why do love triangles always end up in tears? Second Novel is played in visual-novel form which is heavy on the text and static graphics but generally short on actual player interaction.
